Effective December 6, 2021, Spectrum Health Reference Laboratory (SHRL) Coagulation department will go live with a new lot of Prothrombin Time (Protime/PT) reagents. The reference range for the PT will be adjusted to reflect this reagent lot change and align with our Regional Laboratories. The new reference range will be 9.5 – 12.0 seconds. There will be no change to the INR ranges.
| Test | Current Reference Range | New Reference Range |
| Prothrombin Time (PT) | 9.7 – 12.6 seconds | 9.5 – 12.0 seconds |
The supply of the Sofia Strep Test Kits (ITM-1052057) has returned to a stable level allowing the system to migrate back to this Strep Test kit solely. Please note once the remaining supply of the alternative strep test kit (Cardinal – ITM-1157857) is depleted, the item will be inactivated.
Due to this change, please ensure competencies are up to date for the Sofia Strep test kit.
Procedure Reference #17340, #24118.
Test Information:
Effective immediately, Thyroglobulin Antibody will be performed at Spectrum Health Reference Laboratory (SHRL, Grand Rapids, MI) and will no longer be a sendout to Mayo Clinical Laboratories. Collection instructions and other information may have changed, please visit the lab catalog for more information.
Thyroglobulin Tumor Marker will continue to be a sendout. If a Thyroglobulin Antibody is ordered with a Thyroglobulin Tumor Marker, then the Thyroglobulin Antibody will automatically be canceled as Mayo Clinic Laboratories will perform the Thyroglobulin Antibody as well as the Tumor Marker.
For questions and inquiries, please use the “Contact Us” link above.
New test: Thyroglobulin Antibody [LAB1230840]
Former test: Thyroglobulin Antibody, Serum [LAB1230457]
Mentioned Test: Thyroglobulin, Tumor Marker, Serum [LAB864]
In continued pursuit of alignment, regional market hospital labs have adopted the Sysmex-Siemens automated urinalysis system. This advanced platform elevates analytical control and automation, eliminates manual steps previously required from former systems, and offers the latest in digital particle imagery. Combined with exceptional service engineer support, this system represents a notable step forward in urinalysis performance.
The mitigation strategies enacted during the COVID-19 pandemic to reduce the spread of this virus have also impacted the transmission of other respiratory viruses. Influenza is typically prevalent during the winter months (December through March), however, influenza cases were essentially non-existent during the 2020-2021 season and influenza is not currently circulating in our community.
In the absence of circulating influenza activity, it is recommended to use the most sensitive diagnostic test in order to obtain accurate and actionable results. Influenza antigen testing (e.g. Sofia instrument) is not appropriate at this time. More detailed information can be found as published by the CDC: Algorithm to assist in the interpretation of influenza testing results and clinical decision-making during periods when influenza viruses are NOT circulating in the community

Effective September 15, 2021, Spectrum Health’s Epic will contain new ask-at-order questions to help improve clinical decision support and appropriate utilization of stool ova and parasite (O&P) testing. O&P testing may be used to diagnose several parasitic infections, though the staining of stool smears and their microscopic review is very labor intensive for laboratories. Historically, O&P testing has been widely ordered for patients with diarrhea, however, there are now other testing options able to detect the most common pathogens associated with community-acquired diarrhea. While Enteric Pathogens PCR and Giardia/Cryptosporidium testing is more appropriate for the identification of common bacterial/viral and parasitic pathogens, respectively, O&P testing should be reserved for patients with specific exposure or immune status criteria.
The Pharmacy and Infectious Disease Stewardship Committee has endorsed the following order criteria for O&P testing. If any of these criteria are met, then then order can be placed.
♦ Past foreign residence or recent foreign travel followed by at least 2 weeks of diarrhea.
♦ Immunocompromised status.
♦ Unexplained microcytic anemia or peripheral eosinophilia.
♦ Unique exposure (daycare, MSM, waterborne outbreak, etc.)
Note: If no criteria are met, cancel the order and consider Giardia/Cryptosporidium Screen (LAB258) or Enteric Pathogens PCR testing (LAB3618).

If you are collecting COVID-19 swabs in your office or clinic, please order and collect using the saline swab kits (“liquid media” or “wet collection”) instead of the tube with no liquid media (“dry collection”).
• Liquid media swab kits will provide a faster turn-around time.
• Dry collection kits supplies are low.
Please refer to the COVID-19 PCR test in the Lab Catalog for the most up-to-date information on COVID-19 collection.
Self-collected vaginal swabs may be used for testing as opposed to provider-collected swabs. Self-collected swabs are supported by current clinical guidelines as recent studies have shown their equivalence, if not superiority, in quality and their association with increased patient satisfaction.
NOTE: Self-collection must still take place in a healthcare setting and is not approved for at-home collection.
